 Following the split from the SPD, the FVdG was increasingly influenced by French syndicalism and anarchism.In 1908, Kater called the Charter of Amiens, the platform of the French General Confederation of Labor (CGT), the earliest and largest syndicalist union worldwide, "a new revelation".Although there was no contact between German "intellectual anarchists" (like Gustav Landauer and Erich Mühsam) and the FVdG, it did have influential anarchist members, most notably Andreas Kleinlein and Fritz Köster.
